It all realy depends on what the devine intervention does if it adds to the story or not.

Deus-ex-machina type devine intervention is never a good story element. However, that isn't the only type there is, and often even devine interention is bound by rules. A good example of great devine intervention as a story tool to kick off the tale is the "Thomas Covenant" serries by Stephen Donaldson. There devine intervention just starts the story, but leaves the main character drifting and unsure of what to do. It creates as many issues as it solves.

Similar in this case. The devine intervention in the plot Ele sketched could simply be that the Sorceress is left behind, dying in a ditch. Isha takes pity on her (for what-ever reason you want to add in) and because she is a goddess for all elves, not just high ones, she saves the sorceress. Without expecting or demanding anything in return, she heal the physical wounds to the point where the sorceress doesn't die anymore.

The DE sorceress then can start questioning everything she believes in and has been brought up with. The selfless act to which she ows her life is completely strange to her. This starts the change, and the rest is up to the sorceress and the story to solve.

Yea, the idea with the Isha scenario is a starting point, the trials and tribulations she would go through trying to be accepted by the Asur, especially the Nagarythii, would end up being the bulk of the story.

ahh, okay, then I can understand it.. the way I envisioned it was that it was somewhere in the middle of the story or something, rather than at the beginning.
But that's sort of because of the multitude of "redemption" stories I've read, written by fans often involve some kind of Dark-elf, who just does everything for senseless reasons and eventually gets this sort of über revelation of all the things she's done and then promptly changes into this happy-go-lucky type of character...
~w~ perhaps I should spend less time reading the fanfics of 12y/o kids...

and if I might add a little tid-bit; do include the reason whý Isha takes pity on her.

The division of the race was a moment of great sadness for Isha, she loves all Elves. Poor Isha, always sad...

Isha treasures life. Life as natural life and death cycle. She hates Chaos. As one of the few she is able to return any creature to their natural state. Chaos gods do not have to like it. The Druchii in question doesn't have to like it. She doesn't unlearn sorcery. So in the end it is she who decides if she accepts the grace or not.
